An equation refers to an equation containing unknowns. It is an equation that represents the equal relationship between two mathematical expressions (such as two numbers, functions, quantities and operations). The process of finding the solution of the equation is called "solving the equation".

"Solution": The solution of the equation refers to all unknowns, and the root of the equation refers to the solution of the unary equation, both of which can be commonly used. Solving an equation: The process of finding the solution of an equation, or the value of an unknown in an equation, is called solving an equation.

The formula for solving this equation is as follows:

The most important thing to pay attention to when solving a linear equation with one variable is: multiply all denominators and put brackets on polynomial molecules; Take off all the brackets, be careful that it is a symbol; Move the term and change the sign, do not miss the term, and know the unknown equal sign; Combine similar items, add coefficients, and remember that the coefficients are 1.

Quadratic equation with one variable has four characteristics: it contains only one unknown; The maximum number of unknowns is 2; This is an integral equation. To judge whether an equation is an unary quadratic equation, we should first look at whether it is an integral equation. If so, then tidy it up. If it can be arranged in the form of ax2+bx+c=0(a≠0), then this equation is an unary quadratic equation. Turn the equation into a general form: when ax2+bx+c=0, it should satisfy (a≠0).
